The multi-genre oddity is also getting a special edition retail release filled with goodies.

March 16th sees the long-awaited release of The Binding of Isaac from Super Meat Boy creator Edmund Mcmillen at Retail.

Along with the bestselling Steam version, The Binding of Isaac is also getting the stacked retail release pictured below. Dubbed "The Unholy Version," it'll contain a DRM-free copy of the game, a Steam gift code, a 40-page "devzine," as well as the game's soundtrack. Here's the story synopsis for the very hard to pin down game:

When Isaac’s mother starts hearing the voice of God demanding a sacrifice be made to prove her faith, Isaac flees to the basement. Isaac must face monster filled dungeons, lost brothers and sisters, his fears, and eventually his mother.

The Binding of Isaac is a randomly generated action RPG shooter with heavy Rogue-like elements. Following Isaac on his journey, players will find bizarre treasures that change Isaac’s form giving him super human abilities and enabling him to fight off droves of mysterious creatures, discover secrets and fight his way to safety.

No price has been announced as of yet for the "Unholy Version," but we'll be on the lookout for an update on that front.
